Does anyone know the current maintenance status of the X11 package? I emailed
Spencer Janssen a number of months ago and never heard back. So, I'll put
this here in case any one else runs into it or can get it to the right place.
This is a proposed bug fix for a problem I ran into using xmonad client
messages to send remote commands on 64LP architectures (i.e., amd64), wherein
the C X11 library and Haskell's disagree about the size of client message
arguments.

* change XClientMessageEvent long data
The XClientMessageEvent.data.l field is actually a long, not an int, so it must
be interpreted as such, even though format is set to 32 in this case.
Ostensibly this is an Xlib bug, but it is unlikely to be fixed there.
